a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
in this study, physiological and morphological responses of five almond cultivars to drought stress were investigated under in vitro conditions. plantlets from five commercial almond cultivars (supernova’, ‘tuono’, ‘sahand’, ‘ferragnes ’ and ‘shahroud 21’] were established in ms medium containing 0.5 mg per liter bap and then subcultured in ms proliferation medium containing 1 mg per liter bap...
Water shortage is one of the most important limiting factors for crop production, that affected growth and yield by changing physiological conditions. This study was carried out to investigate effect of oxidative stress on antioxidant defense mechanism in Research greenhouses of Birjand University in 2014. A factorial arrangement of treatments based on randomized complete block design (Due to...
breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
In order to study effect of drought stress on morphologic traits, yield and yield components of 28 new hybrids of corn to heat and drought stress in addition 6 commercial hybrid (as control), an experiment was carried out on based of complete randomized block design with three replication under normal irrigation and drought stress in Khorasan Razavi Agricultural Research and Natural Resources I...

To evaluate the effect of copper nanoparticles on the characteristics of mallow under drought stress conditions, a factorial experiment was conducted in a completely randomized design with three replications under greenhouse conditions in 2017. The first factor of drought stress was at three levels without stress and 75 and 50% of field capacity and the second factor was copper nanoparticles at...
the aims of this study were to assess the effects of drought stress on peroxidase (pod), superoxide dismutase (sod) and catalase (cat) activities as well as free proline content and growth parameters of pistacia khinjuk seedlings under drought stress. therefore, the one-year seedlings of pistacia khinjuk subjected to water stress (25%, 50%, 75%, and 100% field capacity) for 8 months in greenhou...
photosynthetic characteristics and induction of crassulacean acid metabolism (cam) by drought stress were investigated in sedum album, sedum stoloniferum and rosularia elymaitica from crassulaceae. titratable acidity, malate content, phosphoenolpyruvate carboxylase (pepc) activity and gas exchange parameters were determined in plants at the end and beginning of the photoperiod. results showed t...
